Reconcile() was swallowing errors from ApplyCACerts/ApplyProxy, which are RPC calls to the sidecarexec container. If that container's socket wasn't listening yet (a real container-start race, no ordering guarantee within the Pod), the failure was logged and discarded, so CA certs/proxy could go permanently unapplied for the Pod's lifetime with no retry. Now Reconcile() returns the error so controller-runtime requeues watch- triggered reconciles with backoff, and the one-shot startup reconcile in run.go retries with a bounded backoff instead of silently continuing.
